One-time PIN
A one-time password (OTP), also known as a one-time PIN, one-time passcode, one-time authorization code (OTAC) or dynamic password, is a password that is valid for only one login session or transaction, on a computer system or other digital device. OTPs avoid several shortcomings that are associated with traditional (static) password-based authentication; a number of implementations also incorporate two-factor authentication by ensuring that the one-time password requires access to ''something a person has'' (such as a small keyring fob device with the OTP calculator built into it, or a smartcard or specific cellphone) as well as ''something a person knows'' (such as a PIN). OTP generation algorithms typically make use of pseudorandomness or randomness to generate a shared key or seed, and cryptographic hash functions, which can be used to derive a value but are hard to reverse and therefore difficult for an attacker to obtain the data that was used for the hash. This is necessa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MasterCard SecureCode
3-D Secure is a protocol designed to be an additional security layer for online credit card, credit and debit card transactions. The name refers to the "three domains" which interact using the protocol: the merchant/acquirer domain, the issuer domain, and the interoperability domain. Originally developed in the autumn of 1999 by Celo Communications AB (which was acquired by Gemplus Associates and integrated into Gemplus, Gemalto and now Thales Group) for Visa Inc. in a project named "p42" ("p" from Pole vault as the project was a big challenge and Phrases from The Hitchhiker's Guide to the Galaxy#The Answer to the Ultimate Question of Life, the Universe, and Everything is 42, "42" as the answer from the book ''The Hitchhiker's Guide to the Galaxy''). A new updated version was developed by Gemplus between 2000-2001. In 2001 Arcot Systems (now CA Technologies) and Visa Inc. with the intention of improving the security of Internet payments, and offered to customers under the Verifie ...
